  • Patent number: 12636405
    Abstract: A covering membrane for medical wound area treatment is disclosed for burns or for preventing adhesion. The covering membrane has a substrate layer including a polymer material as well as collagen particles which have a particle size I of more than 80 ?m and are disposed in such a way as to be fixedly embedded in at least some portions of the polymer material of the substrate layer. The covering membrane further relates to a process for manufacturing such a covering membrane.
    Type: Grant

  • Patent number: 5104398
    Abstract: A surgical suturing thread is coated with a fatty acid metal salt. For this purpose it is dissolved in an organic solvent and the suturing thread is coated with the hot solution, whose temperature is so high that the fatty acid metal salt remains in the dissolved state. The solvent is then evaporated from the thus applied coating at elevated temperature.
